· Tl4

Tl4 is a thallium-based compound semiconductor, likely a binary or ternary phase in the thallium material system used in specialized optoelectronic and infrared applications. This material belongs to the family of heavy-metal chalcogenides and halides explored for narrow-bandgap semiconductors, where thallium compounds offer unique optical and electronic properties in the infrared spectrum not easily replicated by conventional semiconductors.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
